Water Quality and Potability
We are collecting a dataset on water quality to train a machine learning model for binary classification: determining whether water is safe for consumption (1) or not (0). This model will help with water treatment decisions and ensure compliance with quality standards. We applied different summarization and plotting methods to help us to understand our dataset, such as scatter, histogram and bar plot. Then, we applyed preprocess in our data using data cleaning, data transformation and feature selection.

Data Transformation:
water_potability$Potability[water_potability$Potability == '0'] <- 'Not Potable'
water_potability$Potability[water_potability$Potability == '1'] <- 'Potable'
water_potability$Potability <- as.factor(water_potability$Potability)
table(water_potability$Potability)
Not Potable Potable
1200 811 print(water_potability)Description: This step involved transforming the class label, Potability, into categorical data. We changed the numeric data to ‘Not Potable’ and ‘Potable’ to indicate whether the water is safe for human consumption, where 1 represents ‘Potable’, and 0 represents ‘Not Potable’.

To produce a more accurate dataset that would help obtain more precise results later, we took the following steps to handle outliers in the numeric attributes. Firstly, we identified all the outliers. Secondly, we deleted the rows containing the outliers. Finally, we conducted a second check to ensure all outliers were deleted. Any new outliers due to the IQR change after deleting rows in the second step were also eliminated.

Scatter Plot
with(water_potability, plot(Turbidity, ph, col = Potability, pch = as.numeric(Potability)))
Description: -Histogram: The histogram shows the frequency of ph in the dataset; we noted that the majority of values fall within the usual range, which is about between 6 and 8, but it also shows several outliers. -Scatter plot: This scatter demonstrates the correlation and proportionality between the two qualities, allowing us to establish whether or not turbidity and pH are connected. -Bar Plot the bar plot represent how ph levels affect water portability in the dataset it indicates that ph level above 10 is not portibal and humans cant consume it
Remove Redundant Features:
correlation_matrix <- cor(water_potability[,1:9])
high_correlation_features <- findCorrelation(correlation_matrix, cutoff = 0.5)
print(high_correlation_features)integer(0)heatmap(correlation_matrix)
Description: This will find the correlation between the features and represent it in heat map
Feature selection
Rank Features By Importance:
#train random forest model and calculate feature importance
rf = randomForest(x= water_potability[,1:9],y= water_potability[,10])
var_imp <- varImp(rf, scale = FALSE)
#sort the score in decreasing order
var_imp_df <- data.frame(cbind(variable = rownames(var_imp), score = var_imp[,1]))
var_imp_df$score <- as.double(var_imp_df$score)
var_imp_df[order(var_imp_df$score,decreasing = TRUE),]
ggplot(var_imp_df, aes(x=reorder(variable, score), y=score)) +
geom_point() +
geom_segment(aes(x=variable,xend=variable,y=0,yend=score)) +
ylab("IncNodePurity") +

Recursive Feature elimination:
control <- rfeControl(functions=rfFuncs, method="cv",number=10)
rf <- trainControl(method = "cv", number = 10, verboseIter = FALSE)
# run the RFE algorithm
rfe_model <- rfe(x= water_potability[,1:9],y= water_potability[,10], sizes=c(1:9), rfeControl=control)
# summarize the results
print(rfe_model)
Recursive feature selection
Outer resampling method: Cross-Validated (10 fold)
Resampling performance over subset size:
The top 5 variables (out of 5):
Sulfate, ph, Hardness, Solids, Chloramines# list the chosen features
predictors(rfe_model)[1] "Sulfate" "ph" "Hardness" "Solids" "Chloramines"# plot the results
plot(rfe_model, type=c("g", "o"))
Description: Ranking features by importance is a technique used to identify the most influential variables in a dataset for predicting a target variable. This process helps understand which features impact the model’s performance most by ranking features by importance.
Removing redundant features means eliminating variables or features from a dataset that do not provide additional or unique information.
Data transformation
Discretization:
wp<- water_potability
wp$ph= cut(wp$ph, breaks = seq(3,11,by=4),right=FALSE)
wp$Hardness= cut(wp$Hardness, breaks = seq(120,280,by=40),right=FALSE)
wp$Chloramines = cut(wp$Chloramines, breaks = seq(3,11,by=4),right = FALSE)
wp$Sulfate= cut(wp$Sulfate, breaks = seq(220,440,by=44),right=FALSE)
wp$Conductivity= cut(wp$Conductivity, breaks = seq(200,700,by=100),right=FALSE)
wp$Organic_carbon= cut(wp$Organic_carbon, breaks = seq(4,24,by=4),right=FALSE)
wp$Trihalomethanes= cut(wp$Trihalomethanes, breaks = seq(20,110,by=10),right=FALSE)
wp$Turbidity= cut(wp$Turbidity, breaks = seq(1,7,by=2),right=FALSE)
print(wp)Description: Discretization is the process of transforming continuous variables into discrete or categorical variables. It can be useful for analyzing data with many unique values or simplifying it. Therefore, we transformed the continuous values of the numeric attributes into intervals by dividing the values to fall on one of the possible interval labels by discretization. The values will be meaningful and simpler to classify or perform other methods to help us later in our model. So, In Trihalomethanes, we intervals by dividing the values by 10 to have labels with equal width : [20,30) [30,40) [40,50) [50,60) [60,70) [70,80) [80,90) [90,100) [100,110).
Normlization
normalize=function(x){return ((x-min(x))/(max(x)))}
wp$Solids=normalize(wp$Solids)Description: Normalization refers to the process of scaling variables to have a common range. It helps in comparing variables with different scales. The solids attribute will create critical challenges because of the vast and diverted values: min is 320.9, and max is 43195.5, so we normalized the solids between 0 and 1 to make values smaller and more reasonable.
Encoding
Description: Encoding is converting characters or strings into a specific encoding format. We could not implement it since our database does not have a Nominal attribute.

We are collecting a dataset on water quality to train a machine learning model
for binary classification: determining whether water is safe for consumption (1)
or not (0). This model will help with water treatment decisions and ensure
compliance with quality standards.
We applied different summarization and plotting methods to help us to understand
our dataset, such as scatter, histogram and bar plot. Then, we applyed
preprocess in our data using data cleaning, data transformation 
and feature selection.

Checking for missing values:
```{r}
dim(water_potability)
sum(is.na(water_potability))
```
Remove rows with missing values
```{r}
colSums(is.na(water_potability))
water_potability = na.omit(water_potability)

colSums(is.na(water_potability))
View(water_potability)
```
Description:
The absence of data in certain variables or columns in a dataset is referred to as missing or null values due to various reasons.  It can have a negative impact on the dataset's efficiency and the information that can be taken from it later, so we checked to see whether our data had missing or null values and eliminated these rows to produce a more efficient dataset.

```

Descriotion:
With using minimum, maximum, mean, median laws it helps to provide an overview of the data's key characteristics

Data Transformation:
```{r}
water_potability$Potability[water_potability$Potability == '0'] <- 'Not Potable'
water_potability$Potability[water_potability$Potability == '1'] <- 'Potable'

water_potability$Potability <- as.factor(water_potability$Potability)
table(water_potability$Potability)
```
```{r}
print(water_potability)
```
Description:
This step involved transforming the class label, Potability, into categorical data. We changed the numeric data to 'Not Potable' and 'Potable' to indicate whether the water is safe for human consumption, where 1 represents 'Potable', and 0 represents 'Not Potable'.

```


```{r}
summary(water_potability)
```


```{r}
str(water_potability)
```


```{r}
head(water_potability)
```

Description:
Removing outliers from a dataset is critical for assuring the quality and reliability of statistical analysis and machine learning models. To produce a more accurate dataset that would help obtain more precise results later, we took the following steps to handle outliers in the numeric attributes. Firstly, we identified all the outliers. Secondly, we deleted the rows containing the outliers. Finally, we conducted a second check to ensure all outliers were deleted. Any new outliers due to the IQR change after deleting rows in the second step were also eliminated.



Charts

Histogram
```{r}
hist(water_potability$ph)
hist(water_potability$Chloramines)
hist(water_potability$Hardness)
hist(water_potability$Solids)
hist(water_potability$Sulfate)
hist(water_potability$Conductivity)
hist(water_potability$Organic_carbon)
hist(water_potability$Trihalomethanes)
hist(water_potability$Turbidity)
```

Bar Plot
```{r}
tab <- water_potability$Potability %>% table()
txt <- paste0(tab) 
bb <- water_potability$ph %>% table() %>% barplot( main='ph',col=c('pink'))
bb <- water_potability$Potability %>% table() %>% barplot( main='Potability',ylab='Frequency',col=c('pink', 'lightblue'))
text(bb, tab/2, labels=txt, cex=1)

```

Pie chart
```{r}
water_potability$Potability %>% table() %>% pie()
```

Scatter Plot
```{r}
with(water_potability, plot(Turbidity, ph, col = Potability, pch = as.numeric(Potability)))
```
 
Description:
-Histogram:
  The histogram shows the frequency of ph in the dataset; we noted that the majority of values fall    within the usual range, which is about between 6 and 8, but it also shows several outliers.
-Scatter plot:
  This scatter demonstrates the correlation and proportionality between the two qualities, allowing    us to establish whether or not turbidity and pH are connected.
-Bar Plot
  the bar plot represent how ph levels affect water portability in the dataset it indicates that ph    level above 10 is not portibal and humans cant consume it 



Remove Redundant Features:
```{r}
correlation_matrix <- cor(water_potability[,1:9])
high_correlation_features <- findCorrelation(correlation_matrix, cutoff = 0.5)
print(high_correlation_features)
heatmap(correlation_matrix)
```
Description:
This will find the correlation between the features and represent it in heat map



Feature selection

Rank Features By Importance:
```{r, warning=FALSE}
#train random forest model and calculate feature importance
rf = randomForest(x= water_potability[,1:9],y= water_potability[,10])
var_imp <- varImp(rf, scale = FALSE)
#sort the score in decreasing order
var_imp_df <- data.frame(cbind(variable = rownames(var_imp), score = var_imp[,1]))
var_imp_df$score <- as.double(var_imp_df$score)
var_imp_df[order(var_imp_df$score,decreasing = TRUE),]

ggplot(var_imp_df, aes(x=reorder(variable, score), y=score)) + 
  geom_point() +
  geom_segment(aes(x=variable,xend=variable,y=0,yend=score)) +
  ylab("IncNodePurity") +
  xlab("Variable Name") +
  coord_flip()
```

Recursive Feature elimination:
```{r, warning=FALSE}
control <- rfeControl(functions=rfFuncs, method="cv",number=10)
rf <- trainControl(method = "cv", number = 10, verboseIter = FALSE)
# run the RFE algorithm
rfe_model <- rfe(x= water_potability[,1:9],y= water_potability[,10], sizes=c(1:9), rfeControl=control)
# summarize the results
print(rfe_model)
# list the chosen features
predictors(rfe_model)
# plot the results
plot(rfe_model, type=c("g", "o"))
```
Description:
Ranking features by importance is a technique used to identify the most influential variables in a dataset for predicting a target variable. This process helps understand which features impact the model's performance most by ranking features by importance.

Removing redundant features means eliminating variables or features from a dataset that do not provide additional or unique information.



Data transformation

Discretization:
```{r}
wp<- water_potability
wp$ph= cut(wp$ph, breaks = seq(3,11,by=4),right=FALSE)
wp$Hardness= cut(wp$Hardness, breaks = seq(120,280,by=40),right=FALSE)
wp$Chloramines = cut(wp$Chloramines, breaks = seq(3,11,by=4),right = FALSE)
wp$Sulfate= cut(wp$Sulfate, breaks = seq(220,440,by=44),right=FALSE)
wp$Conductivity= cut(wp$Conductivity, breaks = seq(200,700,by=100),right=FALSE)
wp$Organic_carbon= cut(wp$Organic_carbon, breaks = seq(4,24,by=4),right=FALSE)
wp$Trihalomethanes= cut(wp$Trihalomethanes, breaks = seq(20,110,by=10),right=FALSE)
wp$Turbidity= cut(wp$Turbidity, breaks = seq(1,7,by=2),right=FALSE)

print(wp)
```
Description:
Discretization is the process of transforming continuous variables into discrete or categorical variables. It can be useful for analyzing data with many unique values or simplifying it. Therefore, we transformed the continuous values of the numeric attributes into intervals by dividing the values to fall on one of the possible interval labels by discretization. The values will be meaningful and simpler to classify or perform other methods to help us later in our model. So, In Trihalomethanes, we intervals by dividing the values by 10 to have labels with equal width : [20,30) [30,40) [40,50) [50,60) [60,70) [70,80) [80,90) [90,100) [100,110).


Normlization
```{r}
normalize=function(x){return ((x-min(x))/(max(x)))}
wp$Solids=normalize(wp$Solids)
```
Description:
Normalization refers to the process of scaling variables to have a common range. It helps in comparing variables with different scales. The solids attribute will create critical challenges because of the vast and diverted values: min is 320.9, and max is 43195.5, so we normalized the solids between 0 and 1 to make values smaller and more reasonable.


Encoding

Description:
Encoding is converting characters or strings into a specific encoding format. We could not implement it since our database does not have a Nominal attribute.
